Hello and welcome to Just Answer,
Thanks for your question concerning Aria Speedwagon :) I need some additional information to help.
1) Is she responsive if you call her? Does it stop if she is doing something else (i.e. if taken outside to go to potty).
2) Any vomiting or diarrhea?
3) Any chance she could have got into any chemicals, toxins, or drugs?
Reply back and I will try to help.
Thanks for the additional information.
Any chance she is having any nasal discharge? I have seen dogs lick constantly if there is discharge. I have also seen them lick constantly if something is stuck on the roof of their mouth. Take a look if she will let you.
Otherwise, I agree this could certainly be some type of "Focal" seizure. As long as she is not having a full blown grand mal seizure, vomiting, or continuing to have loose stool, it could probably wait until morning, but I do think she needs to be examined by your veterinarian. If they don't find anything on physical exam they will most likely want to run complete blood work (CBC, Biochemistry, T4) to check her out.
Again if she is getting worse, it would be better to get her in sooner than later.
I hope this helps. Good luck with Aria, and let me know if you have additional questions.
Thanks for the additional information. If she is not getting worse and acting ok--ie. eating/drinking & no vomiting/diarrhea, then you could certainly wait until Monday.
Hopefully your veterinarian will be working tomorrow , and it won't be an issue. Again, if getting worse then contact the ER.
Good luck! Let me know if I can help again in the future.
